The Working Days Calculator counts the number of business days between two dates, skipping Saturdays and Sundays automatically. You can also provide a list of public or company-specific holidays to exclude from the count — giving you a precise figure for planning purposes.
Yes. Both the start date and end date are included in the calculation if they fall on a working day. If either falls on a weekend or excluded holiday, it is not counted.
Enter holidays in ISO 8601 format: YYYY-MM-DD (e.g., 2024-12-25). Add one date per line in the holiday input field.
Yes. You can select any start and end date regardless of year span. The calculator handles multi-year ranges accurately, including leap years.
No. If a holiday falls on a Saturday or Sunday, it does not affect the working day count since those days are already excluded as weekends.
No data leaves your browser. The entire calculation is performed client-side in JavaScript. No dates or holiday lists are stored or transmitted.
Yes. Since you enter holidays manually, you can use this tool for any country. Simply look up your country's public holiday schedule and paste the dates in YYYY-MM-DD format.
A working days calculator is a tool that counts the number of business days between two calendar dates, excluding non-working days such as weekends (Saturday and Sunday) and optional public holidays. Unlike simply subtracting one date from another to get total calendar days, a working days calculator gives you a practical figure used in project management, HR, legal, and financial planning contexts.

The calculation iterates through each calendar day in the selected range, from start date to end date inclusive. For each day, it checks two conditions: whether the day falls on a Monday through Friday (weekday), and whether the date appears in the list of excluded holidays. Days that pass both checks are counted as working days.
The result also shows a breakdown: total calendar days in the range, total weekend days skipped, and total holiday dates excluded that fell on weekdays. This gives you full transparency into how the final working day count was reached.
Many real-world processes operate on business day timelines rather than calendar timelines. Here are common scenarios where working day counts are essential:
Every country — and even individual companies — has its own schedule of public holidays and observed days off. The custom holiday feature lets you paste in any dates in YYYY-MM-DD format, one per line. The calculator then skips any of those dates that fall within your selected range on a weekday.
For example, if you are calculating working days in the United States during December, you might add 2024-12-25 (Christmas Day) and 2024-12-26 (any observed day). The calculator will subtract those from the final count, giving you an accurate US business day total for the period.
These three terms are often used interchangeably but have distinct meanings:
For most professional purposes, "business days" is the most accurate measure, and this calculator supports it fully via the custom holiday field.
To get the most accurate working day count, keep the following in mind:
YYYY-MM-DD format exactly. A date like 25-12-2024 will be ignored by the parser.YYYY-02-29.Common public holiday sets by region that you can paste directly into the holiday field include US Federal Holidays (New Year's Day, MLK Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas), UK Bank Holidays, and EU statutory minimums. Many government websites publish annual holiday lists in downloadable formats that you can convert to YYYY-MM-DD and paste here directly.
